Not to flame the Amsoil believer anymore, however, I noticed some discrepancies in his statements, such as....

hotajax- you first stated:

"Now that  my  drive  train warranty expired, I rolled the dice. I use Amsoil Full Synthetic ATF in my Frontier."

then, when challenged, you indicated:

"I have been using Amsoil products for the last 6 years in everything that has any orifice whatsoever.  I have not had a problem with any of them.  I also love the extended drain intervals on just about all Amsoil products."

.....so which is it, if you believe in Amsoil products so vehemently, why would you be "rolling the dice". Other than you must know that just because Amsoil is a quality synthetic lubricant, that it might not be the best lubricant for all applications. If it was, then nobody would buy anything else and Amsoil would have a monopoly on the market. I use Mobil 1 as I have stated before, and if I found that it wasn't working for my application, I'd try and find another synthetic lubricant that works better for my truck. This is because depending on which engine , diff, tranny, a lubricant is, they all have diff properties, clearances...etc. and some oils don't withstand certain stresses as well as others. Also, with the older Frontiers like I have, their oil capacity is relatively small compared to engine size, the newer Frontiers have a better displacement to capacity ratio IIRC. This means that there is less oil to dissipate heat, to suspend contaminants...and so on and so on. Yes, filters are supposed to clean the oil up, but they also have a limited capacity. As a matter of fact, I am looking into a remote oil filter add-on to get almost another quart of oil capacity, because the kit I am looking at uses the same size as teh Fram PH8A, or similiar size filters, if you are familiar, they are a good size filter.

Anyway, I personally don't have a huge problem with Amsoil, I have seen UOA reports and they seem to show well, but there are plenty of other oils that do well also and don't cost as much. I just choose not to buy Amsoil, because I feel it's a bigger hassle than it's worth, for me. If you are interested, there is an ongoing thread with another member and myself, where we are running tests on oils as we drain them, he is testing Amsoil, I am testing Mobil 1 products.

The big point is, hotajax, you are free to put whatever you want in your Nissan, of course the dealer will steer you to their products, why, because they have been engineered by, or in conjunction with OEM standards to meet the needs of the manufacturer. You are warranty free now, so you should have no issues, just don't get all hot under the collar when others disagree with you. Also, you might have been prematurely labeled an Amsoil dealer, because we have had people in the past join the forum and tout Amsoil as almost a cure-all for fuel economy, and whatnot, which can get pretty annoying. Just FIY.
